摘要：
Multi-group magnetic biochar (MMBC) was prepared by encapsulating rice husk biochar (BC) in magnetic nanoiron by the liquid-phase reduction-coprecipitation method. MMBC was characterized, and its adsorption of Pb(II) was investigated. Single-factor influence experiments showed that the efficiency for removal of Pb(II) by MMBC reached 90.85% with a pH of 5.0, an adsorbent addition amount of 1 g•L-1 and a contact time of 2 h. Kinetic analyses showed that pseudo-second-order kinetics express the adsorption process of Pb(II) on MMBC more comprehen...
